⚡ Explorers: Build a Story Spine

A fully interactive A2.2 Kids grammar lesson in the Explorer Club Master Level that turns the when/while tenses into a storytelling tool: the four-line story spine. Students warm up with four questions about interruptions and surprises, then study two clear blocks — The Story Spine (scene with was/were + -ing, interruption with when + past simple, reaction in past simple, and a fun ending, with formula chips and four worked example lines) and When & While — the Joints (a rules table separating when-interruptions from while-parallel-actions, a reaction-verbs row, and a signal-words panel: was/were + -ing, when, suddenly, while, in the end). Ten key words (spine, scene, interruption, suddenly, reaction, moment, jump, scream, laugh, ending) appear in a scrollable table and six review flashcards. The reading is a ~120-word Team File, 'The Picnic Spine', laid out in scene / interruption / reaction & ending sections with eight hover-tooltip words. Practice offers eight contextualised fill-in-the-blank items (was/were, when/while, -ing verbs, reaction verbs, lesson words) with live green/red feedback and a score; speaking gives five spine-building prompts and a five-line model dialogue between Leo and Mia; the writing task is a guided 30–50 word four-line spine about a pet or sibling with a four-point checklist and live counter; and the quiz is eight multiple-choice questions (six on the spine grammar, two on the reading) with explanations, a progress bar, a result circle, and localStorage persistence.
